Reloading with salvaged components from 303 milsurp ammo.

I NEVER worried about 303 brass. Even with all that's been said about neck sizing and O rings and all, I fired mine until I could see the ring start and out it went. Maybe 3 loads...just not worth worrying about.

Y'all must have left all the dog vomit ammo over here. And NO primers.

Well, you gotta admit, you lot gave the poms a hard time once.
Those cases are suffering from age, splitting. If they make it past the first firing ok, then neck anneal, it will sort that problem out.
As to berdan primer supply, another forum recently discussed this problem.
